If tiling, there's no point in skimming the plasterboard.
If you need to tile over skim, technically you need to wait for a month. Common sense says you tile when you're fed up of taking baths and the wall looks dry.

Answered the same question in plastering but if you read it again carefully, I believe he’s not actually skimming the PB.

hi,no need to skim 900 side wall,use tilers primer to seal all the walls 1st,let dry up to an hour depending on room temp,then use tanking all over the shower area ,allow to dry overnight normally,the longer the better,you can buy full tanking systems for shower areas from your local tile shops.

Now you’ve got 2 lots of answers but, thankfully, not that different . But please don't multi post in future, it only causes confusion for the regulars who, mostly, keep a check on all of the forums anyway (or at least I do ); it also goes against forum rules but this time the “mods” missed it!
